Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment, and in particular relates to a low-temperature curing spraying equipment for powder coatings. Background Technology

[0002] Powder coating is a type of coating that exists in the form of solid powder. It does not rely on solvents and is usually attached to the surface of a workpiece through electrostatic adsorption or other methods. After curing, it forms a uniform and tough coating. It has the characteristics of being environmentally friendly and having excellent coating performance. The use of low-temperature curing spraying equipment is mainly because traditional high-temperature curing methods may cause deformation and cracking of temperature-sensitive substrates such as plastics and wood, affecting product quality. At the same time, low-temperature curing can reduce energy consumption, meet the requirements of energy conservation and environmental protection, and allow powder coatings to be used in more material processing scenarios, thus broadening its application range.

[0003] However, existing spraying equipment is difficult to fix objects of different sizes during use, which causes the workpiece to shift and shake during the spraying process, resulting in uneven coating thickness, local missed spraying or over-spraying, affecting the appearance and performance of the product.
